To all whom itmwy concern:

Be it known that I, JAMES H. Sums, a'oitiresiding at Mobile, in the county ci Mobile and State of Alabama, have invented a new and useful Valve, of which the following is a specification. 'This invention relates to valves, and in particular to supply-valves of closet-cisterns,

and-.has for its object to, provide la novel andusetul arrangement of valve-seat whereby the latter may be removed and replaced without removing the entire valveecasing from the tank. y

`It is furthermore designed to enable the convenient assemblage of the valve-seat with from. the under side of the tank or cistern when the water-supply pipe inater more 25 In the accompanying drawings,

'-tion, size, and

is disconnected therefrom without in any manner interfering with the other portions of the flushing apparatus.

With these and other objects in view the present invention consists in the combination ,"and'arrangement ofparts as will be herefully described, shown in the accompany' drawings, and particularly pointed out in understood that changes in the form, proporminor details may be made Within the scope parting 'from the spirit or sacrliicing any of the advantages of the invention. i Figure 1 is a sectional view taken through the closet-cistern having 'a conventional form oi flushing mechanism to illustratethe general location of the present invention. lii 2' is an enlarged elevation oil the supp y-valve with arts broken awayT to disclose the removable valve-seat'of. the prese t inventiont. Fig. 3 is an enlarged detail-perspective view of the improved valve-seat.

Like characters'o reference designate corresponding parts in' each 'and every figure of the drawings.l

The valve-seatof the present invention consists of a hollow-cylindrical member 1, (shown in detail in. Fig. 3 of the drawings,) the bot tom 2 of thecylinder being closed and provided withfa screwsdriver seat or groove 3.1 5c

bei' constitutesthe valvefseat proper and is vpreierably beveled or tapered inwardly l "4. Adjacent the upper end of the cylinder The-upper openend. the cylindrical meinof the latter is threaded, as'at 5,

the exterior y:and below' this threaded portion 'the cylinder the appended claim, it being of the'claim without de- 13 by any vexit thereof. It will is externally reduced 'and provided with substantially radial openi s or periorations 6.

To illustrate the ap lication of the present 'shown in hig. 1 o

valve-seat, there has een the drawings a flushing-tank 7, having an in-l let-pipe 8 and an outlet or flushing pipe 9, the

inlet-pipe being controlled by a valve inc iid-1.

ing a casing 10,l upon which is fulcrumed e valve-controlling lever 11, carrying a float 12 in the usual or any preferred manner; Upon reference to Fig. -2 of the drawings itwillbe noted that .the valve-casing 10 has a tubular shank portion `1 3 which pierces the bottom of the tank and is externally threaded for the4 receptionoi a nut 14 to clamp thb bottoni of the tank between the nut and the annular v.

Bange 15 upon the bottom ofthe valve-case, whereby the latter is rigidly connected to the 17, whereupon the apparatus is'in operable condition.

n practice water .risingthrough the supply-pipe 8 passes-into'the annular s ace between the reduced lower portion of tiie cylindrical seat member and the tubular shank 13 of the valve-case,A wardly through the opening G'into .the inte rior oi' the valve-seat member and thence up and out through the ere b e explained that it is proposed to employ a screen-covering for the openings or perforations exclude sand and lthe like from the interior of the tubular valve member, and thereby to prevent undue wear of the valve-seat.

wardly into the, casin Whenit becomes necessary to replace thev 17 is disengaged y valve-seat, the coupling from the tubular shank A13 and the supplypipe 8 moved to one side of tlie/ tank suiliciently to enable the introduction of a screw- Idriver into the open lower endv oi the tank for engagement with the screw-,driver seat 3 in the bottom of the valve-seat member,

from whiclrit passes in and the. improved valve-seat of editable form of coupling member 16, so as'to y parts of the flushing Jvention hasl been particularly designed for;-

v fuse Without v:tion therein beyond t.

, lthough it v*r'fitting/of the seat .member to tliecsse.

'noted that the valve-seatI member may Abe f adjusted -endwise @of "bhe ease l0 to enable the "ment of the' valve with the -a bparticularly advantageous 'whereupon the letterfmay be unscrewed and pp'lication'tosiipplyw'alves now in common f vrequurln zany material alteran I needing-the interior of f the tubular shaziks thereof. It Will here Vbe f tubulin: shank lproper engageL seat, this being feature when the seat has become worn, alin the origii'ial 'Within the While the valveseat 4 has been shown l lconoaved, .it may also be flat or convex, as may be desired. I l y lt is Aproposed to have .the perforations 6 in l t lle-member l screened, seas to exclude sand.;

and ,other sediment from passin f into and 4collecting lwithin said member, ft iis feature Ebeing-carried out bymeans of a sheet oiwire ggluae or the likell, snugly embracing the vperforate portion o the member l and secured thereto in any suitable manner-f0r instance, by beingr soldered thereto.

Having i'ullydescribed the invention, what is claimed is- Avalve comprising a case open at one end andhaving an internally-threaded portion, said ease being of uniform internal diameter, a tubular valve-seat member having its inner 4end open and constituting the valve-seat pro er, said inner nal' threaded portion. of

end portion being,r cx ter- :portion of the valve seat being reduced and V of uniform diameter to form an annular space tlierearound, said reduced portion belng provided with one or more perforations, the upper end of the valve-seat member bej ing closed and provided With a screw-driver f seat accessible 'through the open end of the case, the adjustment oisaid valvefseat mein- I er being constantly' unobstructed, and a tubular Iscreen surrounding the reduced portion of the valve-seat member and having its internal ydiameter substantially .equal to the external diameter-of said portion.

ln testimony that I claim the `foregoing as my own'I have hereto affixed my signature 6o in the presence of two Witnesses.
